IFRS 10 Control — Core Rule

Under IFRS 10, an investor controls an investee — and must consolidate it — only when all three elements are simultaneously present: power over the investee, exposure or rights to variable returns, and the ability to use power to affect those returns (IFRS 10.7).

How IFRS 10 Control Works

• Element 1 — Power (IFRS 10.10–14): An investor has power when it holds existing rights that give it the current ability to direct the relevant activities of the investee — those activities that most significantly affect the investee's returns. Rights conferring power include voting rights (IFRS 10.B34), contractual rights to appoint key management, or design-stage rights embedded in structured entities. Potential voting rights are included only if they are substantive, not merely protective (IFRS 10.B47).

• Relevant activities defined (IFRS 10.B11–B13): These are operating and financing decisions that most significantly affect the investee's returns — for example, setting strategic direction, approving capital expenditure, or managing credit exposures in a structured entity. Identifying relevant activities is the pivotal first step before assessing who controls them.

• Element 2 — Exposure to variable returns (IFRS 10.15–16): The investor must be exposed, or have rights, to variable returns from its involvement. Returns must be variable (not fixed) and can be positive, negative, or both. Examples include dividends, fees, residual interests, tax benefits, and guarantees that expose the investor to loss (IFRS 10.B56–B57).

• Element 3 — Link between power and returns (IFRS 10.17–18): The investor must have the current ability to use its power to affect the amount of its own returns. This element distinguishes a principal (who consolidates) from an agent (who does not). An asset manager with discretionary authority but remunerated only by a market-rate fee may be an agent; its power is exercised on behalf of other parties (IFRS 10.B58–B72).

• Continuous reassessment (IFRS 10.8): Control must be reassessed whenever facts and circumstances indicate a change — for example, a new shareholder agreement, dilution of voting rights, or a change in the investee's purpose. The assessment is not a one-time exercise at acquisition.

• Consolidation mechanics (IFRS 10.19–26): Once control is established, the parent consolidates line-by-line, eliminating intragroup transactions, and recognises any non-controlling interest (NCI) either at fair value or at the NCI's proportionate share of net identifiable assets (IFRS 3.19).

IFRS 10 Control — Practical Example

Scenario: Alpha plc holds 45% of Beta Ltd's voting shares. The remaining 55% is dispersed among hundreds of small shareholders with no history of coordinated voting. Alpha appoints Beta's CEO and CFO under a management agreement and receives a variable performance fee plus its share of dividends.

Control assessment

• Power: Alpha directs Beta's relevant activities (hiring key management, approving budgets) via de facto power — a majority at general meetings is consistently achievable given shareholder dispersion (IFRS 10.B42–B45). ✓
• Variable returns: Alpha receives dividends (variable) and a performance fee that fluctuates with Beta's profitability (IFRS 10.B56). ✓
• Link: Alpha uses its managerial power to drive profitability, directly affecting the size of its dividend and fee income (IFRS 10.17). ✓

Conclusion: Alpha controls Beta and consolidates it. On acquisition date (assume net assets of Beta = €10m at fair value, purchase price for 45% = €5m, NCI measured at proportionate share = 55% × €10m = €5.5m):

IFRS 10 Control — Common Pitfalls

• Conflating majority ownership with control: Holding >50% of voting shares creates a rebuttable presumption of power, but IFRS 10 requires all three elements. Conversely, a 30% stake with de facto power (IFRS 10.B42) can still trigger consolidation — practitioners often miss the de facto power analysis entirely.

• Agent/principal confusion (IFRS 10.B58–B72): Fund managers frequently err by concluding they control funds they manage. The key test is whether the decision-maker's exposure to variable returns is significant enough that it is acting as a principal. Four factors must be weighed: scope of authority, rights held by other parties, remuneration, and exposure to variability from other interests.

• Ignoring reassessment triggers (IFRS 10.8): Failing to reassess control when a convertible instrument becomes exercisable, when a veto right lapses, or when a shareholder agreement is renegotiated is a common audit finding and can result in a restatement.
